I love my Bamix stick blender. Supposedly, on the high setting, a Bamix spins something like 10x faster than any other stick blender. I don't know whether that's true or not but I know I can make OO mayo in 15 seconds. Also, it comes with a grinder attachment that's great for making almond flour.

I second David K on the deep fryer - wonderful for wings, LC popcorn shrimp and veggie frites.
